Analysis Of Influencing Factors Of Pregnancy After Tubal Anastomosis

Objective: To explore the related factors influencing pregnancy after tubal anastomosis and improve the pregnancy rate.Methods: 99 women of tubal ligation in our hospital who underwent tubal anastomosis from October 2012 to January 2018 and sustained trying to conceive for at least 1 year were analyzed retrospectively.To analyze the correlation of surgical method,Patency during operation,age,body mass index,sterilization time,anastomotic site,postoperative tubal length,fallopian tube score and postoperative pregnancy.All data were analyzed using SPSS 22.0softwareResults:(1)The pregnancy rate after tubal anastomosis in our hospital was56.57%.(2)There was no significant difference in pregnancy rate between transabdominal micro tube anastomosis and laparoscopic tube anastomosis(P >0.05).(3)There was no significant difference in pregnancy rate between unilateral and bilateral tubal patency(P > 0.05).(4)The highest pregnancy rate of patients under 35 years old was 76.92%.The pregnancy rate of patients under 35 years old and 35-40 years old group was significantly higher than that of 40 years old group(P < 0.0167).(5)The pregnancy rate of BMI normal group was higher than that of hyperrecombination(P < 0.05).(6)The lowest pregnancy rate was 33.33% in the group with sterilization time more than 10 years,which was statistically significant compared with the group with sterilization time less than5 years and 5-10 years(P<0.0167).(7)The pregnancy rate in the isthmus-isthmus group was significantly higher than that in the ampulla-ampulla group(P <0.0167).(8)The pregnancy rate was the lowest in the group with the length of fallopian tube≤7cm,which was statistically significant compared with the groups with the length of 7<L≤ 9cm,9<L≤11cm and > 11cm(P < 0.0125).(9)The pregnancy rate of mild group was 75.47%,which was significantly higher than that of moderate group and severe group(P < 0.0167).(10)Multivariate logistic regression analysis showed that,Age is the risk factor for pregnancy.For every 1year of age adding,the risk of pregnancy increases by 1.383 times;Postoperative tubal length was a protective factor for pregnancy.for every 1 cm increases in postoperative tubal length,the risk of pregnancy decreased by 1.48times;Fallopian tube score is a risk factor of pregnancy,compared with mild,the risk of pregnancy of moderate group increased by 4.352 times,the risk of pregnancy of severe group increased by 33.139 times.Conclusion: The older the age,the higher the fallopian tube score,the lower the pregnancy rate after tubal anastomosis;the longer the retained tubal length after anastomosis,the higher the pregnancy rate after tubal anastomosis.
